Thickener for clear low pH exfoliating cleanser?
Any good options for thickeners in a pH 3.5 glucoside based cleanser? Ideally able to generate a clear or clear ish solution?
Xanthan Gum isn’t very stable at that pH, Carbomer is not suitable, Sclerotium Gum isn’t clear and leaves a lot to be desired texture wise although it is acid stable, acrylate polymers might hurt TEWL over time according to some research.
Any other options?

The Ultrez and the smart lines of lubrizol.

Try one of the Celluloses - Methocel https://www.dow.com/dowwolff/en/industrial_solutions/product/methocel.htm

Sepimax Zen is a polymer thickener that can be used in extremely low pH formulations. It can be used in surfactant systems too.

HEC? HPMC?

Thanks, which smart line from lubrizol @DAS?
Peg-120 Methyl Glucose Dioleate might also be a good choice here. HEC and HPMC hasn’t worked well in the past, makes a very granular solution.

@em88 bang on money here, Methocel 40-101 would be a great choice I suppose. Need slight neutralization, and back acid neutralization is much easier without any loss of viscosity. I have based my comments on a trial for hand sanitizer free of water ethanol having CHG. Cellulose are a liitle slimy in application IMO but they can be worked around as well. Did a beard wash with HEC and an APG, worked fine.
